UNITED STATES FREDERICK BENSON, OF SAN FRANCISCO, CALIFORNIA.

EGG BEATEB.

Application filed July 5,

To all whom it may concern:

Be it known that I, FREDERICK BENSON, a citizen of the United States,and a residentof San Francisco, county of San Francisco, and State ofCalifornia, have invented a new and useful Beater, of which thefollowing is a specification.

This invention relates to egg beaters and has for its primary object theprovision of a device of this character which is simple of construction,positive and quick of action, and which will consist of coactiirg partswherein continuous rotary action of a hand-controlled element will beconverted into oscillatory motion and applied as a motive means to drivethe agitator of the device.

A further object of the invention is to provide a device of thischaracter which, aside from its reliability of action, will consist ofparts that are designed and relatively associated, whereby same will notbe pre-c maturely disorganized and wherein such parts will. not bestrained seriously during ordinary use of the device.

In the drawings:

Figure 1 is a vertical section through the device with parts in fulllines;

Figure 2 is a front elevation of the device.

In carrying the invention into practice I use a frame (5) having a yoke(6) at its lower end which terminates in a combined foot and bearing(7). Said frame is provided with a vertical arm (8) which terminates atits upper end in a hand hold (9). Intermediate of its ends the said arm(8) is offset at (10). Mounted upon a hearing pin (11) on the arm (8) ata point above said offset portion (10) is a rotary wheel (12) having acrank handle (13) whose pin (14:) is provided with an annular groove(15). The grooved portion of this pin is accommodated by the elongatedslot (16) in an oscillating arm (17 This arm is mounted to rock on a pin(18) carried by said offset portion (10) of the bracket. The lower endof this oscillating arm is provided with an arcuate rack (19) or theequivalent thereof. This rack is super- 1923. Serial No. 649,571.

posed with respect to a lateral bearing extension (20) which is locatedat the joinder of the arm with the yoke Passing through said bearingextension (20) is a shaft (21) whose upper end is provided with a gearwheel (22) in mesh with the teeth (23) of said rack (19).

Said shaft (21) is permanently fixed at (22) to the cross bar (2 1) ofan agitator (25). The cross bar (26) of said agitator is connected by abearing pin (27) with the aforesaid foot (7) of the yoke (6). Thisagitator consists of arcuate blades (28-28) which are preferablydiametrically posi tioned, and as illustrated these blades are providedwith effective agitating ribs or flanges (29) which are perforated as at(30).

From the construction described herein itis seen that continuousrotation of the crank wheel (12) will impart continuous 0scillations tothe arm (17) and that incident to the coacting relation of the rack (19)to the agitator the latter will be continuously oscillated. In. otherwords, rotary motion of the said crank wheel (12) will be instantlyconverted into oscillatory motion at the agitator. I find that anagitator which is oscillated as aforementioned is exceedingly positiveand effective of action, and that by gearing the agitator to theoscillating arm (17) in the manner herein stated, the device can besubjected to unusually rough usage without causing the coacting parts ofthe device to be freely dislocated. While I have described that theoscillating arm (17) is provided with an integral arcuate rack which Iemploy as a power transferring means between the crank wheel (12) andthe agitator (25), I will have it clearly understood that changes withinthe scope of the appended claim may be made without departing from thespirit of my invention. In other words, in lieu of an integral rack, thelower portion of the arm (17) may have its ends connected by a chain andthe latter may be in constant mesh with a sprocket wheel on the upperend of the agitator shaft (21').

I claim:

An egg beater comprising a frame formed of a single piece of metal bentto provide a yoke having ahorizontal foot at its lower end, a lateralbearing extension disposed in parallel spaced relation to the foot, andan arm having an offset portion; an agitator shaft journaled in the footand in said extension, a rocker mounted to oscillate on said offsetportion and provided with a gear surface, agear on the agitator shaft inmesh with said gear surface, an agitator on said shaft, and a crankwheel mounted to rotate on said frame and having a driving connectionassociated with said rocker to actuate same.
